In this paper, we investigate some qualitative properties of a class of nonlinear singular systems with multiple constant delays. By using the Lyapunov-Krasovskii functional (LKF) method and integral inequalities, we obtain some new sufficient conditions which guarantee that the considered systems are regular, impulse-free and exponentially stable. Two numerical examples are provided to illustrate the application of the obtained results using MATLAB software. By this paper, we extend and improve some results in the literature.
